Description.

Measurements and ratios (holotype):BL 6.88, HL 1.00, HW 1.11, PL 1.27, PW 1.15, EL 1.36, HL/HW 0.91, HW/PW 0.96, HL/PL 0.79, PL/PW 1.11, EL/PL 0.71.

Male (Fig. 1A). Body brown with paler apex, legs reddish brown, antennae reddish brown to yellowish brown.

Head quadrate; posterior angles broadly rounded; postgenae weakly convex ventrally; integument with coarse and moderately dense punctation; eyes reduced.

Pronotum slightly stocky, slightly broader than head; punctation sparser than that of head; interstices shining, lacking microsculpture.

Elytra at suture distinctly shorter than pronotum; wider than long; punctation well-defined; and hind wings completely reduced.

Abdomen with dense pubescence; sternite VII (Fig. 3A) with short dark modified setae on postero-median semicircular impression; sternite VIII (Fig. 3C) with triangular emargination and with short dark modified setae on deep impression; sternite IX (Fig. 3B) asymmetrical; aedeagus (Fig. 3D, 3E) with conspicuously long, slender ventral process and twisted dorsal sclerites.

Female. Unknown.

Distribution.

East China (Zhejiang: Longwangshan Mountain).

Etymology.

The species is named after Rui-Fen Ling, who collected the type specimens.

Remarks.

The new species is close to Lathrobium fengae in similar general form. Lathrobium lingae differs especially by the male sternite VII with deeper impression, male sternite VIII with regularly triangular apico-median emargination, and aedeagus with gracile ventral process and single dorsal sclerite. Lathrobium fengae has the male sternite VII with shallower impression, male sternite VIII with irregular apico-median emargination, and aedeagus with broad ventral process and two dorsal sclerites.
